Required knowledge

The basic knowledge of the Configuration and Use of the Mobile Panel 277FIWLAN application description is assumed.

2.2 Description of the core functionality

The core functionality is the communication between the mobile panel and severalaccess points that are in a network.It is possible to change from one access point to another access point withoutprevious logoff or new logon.

The mobile panel communicates is expanded byiPCF-MC (industrial Point Coordination Function with Management Channel)WLAN access procedure also called Rapid Roaming.

Rapid Roaming is used for interruption-free transfer of radio signals and providesrapid transfer of radio signals between the access points and the mobile panel abasic requirement for mobile solutions for operating and monitoring in safety-relevant areas where enabling and emergency stop buttons are used.

3 BasicsThis chapter contains information regarding Roaming with iPCF-MC andapplicable WLAN standards.

3.1 iPCF-MC concept

For failsafe applications the mobile panel communicates through the expandedWLAN access procedure iPCF-MC(industrial Point Coordination Function with Management Channel).

The data communication is performed on the so called data channel (in PCFmethod).The coordination of the communication is performed on the so calledmanagement channel.

The figures below are to illustrate the iPCF-MC concept.

Figure 3-1

Each access point has a different "Data Channel"

Each access point has the same "Management Channel" (here channel 48)

AP: Access Point

There are as many data channels (here 36; 40; 44) as there are access pointsand one joint management channel (here 48).

Each access point (AP) sends so called beacons (approx. every 5ms) to themanagement channel.The clients (in this application the mobile panel) receive information regarding the

reception quality and the number of the data channel to all the access points ofthe network in reach within a very short time.

Roaming with iPCF-MC, sequence description

The mobile panel regularly changes from the data channel to the managementchannel and evaluates the received beacons.

In this case the beacon of access point 1 (AP1) is the strongest=> no roaming.

iPCF-MC general conditions

For the operation of iPCF-MC the following general conditions are required:

at least three unused non-overlapping channels are required

the management channel must not be operated on 802.11h (radar detection!)

management channel and data channel must be precisely overlapped:

both must either be in 2.4 GHz band or in 5 GHz band

with the access point, WLAN1 and WLAN2 have to be equipped with thesame antennas

Channel assignment for extensive plants

When configuring the data channel, ensure that the addresses of neighboring datachannels do not overlap.
